Abstract (en)
In an arrangment including ejection electrodes (7; 70) arragned along ink paths (11) having ink outlets (4) at one end and communicating with an ink chamber (6) at other ends, and a grounded opposing electrode (2b) arranged in opposition to the ink outlets with a sheet transfer route in between, the ejection electrodes (7) are settled into electrode sets each consisting of a number of ejection electrodes, the electrode sets having their corresponding ejection electrodes short-circuited, and provided with control electrodes (8) each common to respective ejection electrodes of a corresponding electrode set and rearwardly offset front ends (7a; 70a) of the ejection electrodes in an ink discharge direction, and a voltage driver (13) selectively imposes a voltage (Vr) to electrode groups each consisting of the short-circuited ejection electrodes to have a discharge biasing function and selectively sets a lower potential (Poc) than a potential (Pr) of the ejection electrodes to the control electrodes to have a discharge restricting function. <IMAGE>
